Greetings Nowhere Man, et al:
On one hand, MILSPEC EMP specifications are likely written by DOD professionals to unimaginable CYA standards. On the other hand, consumer device specifications are written by electrical engineers complying with both FCC electromagnetic noise standards and a more important protection of the consumer brand name intergity.
EMP is electromagnetic noise. My understanding of EMP vulnerablity is an inadequately shielded electronic device may fuse open and/or closed unexpectedly from the sudden induced flow of electrons. So I often wondered if the simple metal electric cabinets which the grid switchgear protection devices actually reside within are adequate EMP protection.
In many cases, sloppy install jobs and/or unprofessional repairs render the electromagnetic protection shield non-functionable. Which may explain an occasional electric grid failure during a solar flare event.
An EMP will necessarily trip overvoltage/undervoltage and overcurrent protection relays plus lockout relays grid wide. Just as the transmission line failure caused in summer 2003; a grid reset and restart will take some time.
This EMP talk makes me believe another crony-capitalist company, such as GE, is only trying to hyperpanic sell the USA upon unnecessary EMP protection. Yeah, all this “green energy” propaganda “for the children” makes me very skeptical.
Cheers,
OLA
Also in the case of cars, even though they are run by computers, they are designed to run under rough conditions, heat, cold, high RF environment and so on so perhaps there is a way they can handle EMP as well. I’m into auto parts so I generally know what car parts go through.
